POLYFLOW 3.9 was released in April 2002. Since then, developers have
been working to implement numerous features for the next version, POLYFLOW
3.10. Some of the key capabilities to be included are enhancements to
the adaptive meshing routines, the ability to perform fluid structure
interaction (FSI) calculations, and some preliminary optimization features.
In addition, localized versions of POLYMAN will be introduced. Available
in English, French, and Japanese, this new environment allows users to
start GAMBIT, POLYFLOW, and FIPOST in a Windowslike environment.

One important enhancement in the new version will be the ability to specify
a slippage between the fluid and a driving wall, such as an impeller or
rotating screw. This feature should improve the accuracy of results for
twin-screw extruders, batch mixers, and other equipment that is modeled
using the mesh superposition technique. Viscoelastic modeling options
will be more comprehensive in POLYFLOW 3.10 with the addition of the discrete
elastic viscous stress splitting, or DEVSS1 formulation, available through
the graphical user interface. This model complements the elastic viscous
stress splitting, or EVSS technique, which is currently available.
In response to user requests, POLYFLOW 3.10
will be fully compatible with LINUX RH7.1.
Preliminary tests report encouraging performance
on this platform.
